Biosurfactants interest is increasing in recent years because they are biodegradable, low toxicity, and environmentally friendly. Biosurfactants usage as environmentally friendly oil based mud (OBM) displacement spacers has not been explored. Preliminary experiments showed that these biosurfactants were very effective as OBM displacement spacers with results comparable to incumbent products. Biosurfactants usage as environmentally friendly drill cuttings cleaning has not been explored. Biosurfactants (sohorolipids, rhamnolipids, mannosylerythritol lipids, and non-ionic surfactant from vegetable oil) could be used as an efficient method for treating contaminated drill cuttings.
